The Browns may be unfamiliar with the no-huddle offense, but that's wasn't any excuse for a meltdown a little more than halfway through Sunday's lone practice.

Rookie center Alex Mack was the first offender, messing up the snap count as a defender rushed quarterback Derek Anderson unblocked. Ten-year veteran Hank Fraley was summoned as Mack took a lap. A few plays later linemen Isaac Sowells and Kurt Quarterman were flagged for penalties and joined Mack. Then Fraley's snap went into the ground.

That was the last straw for coach Eric Mangini, who sent the entire offense on a lap around the field. Anderson set a decent pace, with the lineman bringing up the rear. Defensive back Corey Ivy enjoyed the offense's misery, slapping their hands as they went by and saying, ''Pick it up, George,'' to George Foster.

''They should have (run),'' linebacker D'Qwell Jackson said. ''That two-minute, they threw flags all over the place.''

Left guard Eric Steinbach agreed.

''It got pretty sloppy towards the end,'' he said. ''As practice went on, it kind of fell off, guys were jumping offsides, the ball was on the ground too much. I can see why the whole offense went.''

Who's not practicing: Arguably the Browns' top two players were sidelined as defensive lineman Shaun Rogers (presumably hurt on Saturday) rode the exercise bike next to receiver Braylon Edwards (on the reserve-non-football injury list with an undisclosed ailment). Rookie cornerback Don Carey was nowhere to be found after hurting his left shoulder Saturday. Returning was rookie cornerback Coye Francies, who began camp on the same list as Edwards.

QB update: Anderson clearly had the upper hand in the competition with Brady Quinn. Anderson's body language has changed dramatically since the June minicamp, when he looked like he didn't want to be in Cleveland any longer. On Sunday, he was sharp, decisive and managed the team well, especially in the two-minute drill. During seven-on-seven, he threw touchdowns on three of four snaps he took (finding rookie running back James Davis, tight end Aaron Walker and tight end Robert Royal). Anderson received a low five from offensive coordinator Brian Daboll after the throw to Royal.

To end the practice, both quarterbacks got a chance in the 2:00. Quinn faced the first-team defense and failed to score. His series ended on fourth-and-15 when he found receiver Lance Leggett open, but the throw was behind Leggett and out of reach. On Anderson's chance against the second team, he marched the team down the field. On the final play, with 20 seconds left, he found receiver Joshua Cribbs for the touchdown, Cribbs catching it just as the theme from ''Rocky'' came on the loudspeaker. Defensive coordinator Rob Ryan threw his cap to the ground in disgust.

Defensive stars: Defensive lineman Robaire Smith (who tore his Achilles last September) had a good takedown in one-on-one tackling drills and Jackson batted down an Anderson pass. But cornerback Brandon McDonald survived an aerial onslaught from Quinn to Leggett. Quinn threw to Leggett deep on four of six consecutive passes and Leggett caught none. McDonald recorded two good breakups, Leggett dropped one and cornerback Eric Wright, defending on one, was flagged for interference.

Quote of the day: Coach Eric Mangini said emphatically he will not use a two-quarterback system this season, but does not anticipate trading the loser of the competition. ''In my mind, Brady and D.A. will both be here,'' Mangini said.

Celebrity watch: Ryan's father, Buddy, the former coach of the Arizona Cardinals and defensive coordinator of the Super Bowl champion 1985 Chicago Bears, arrived for a five-day stay and watched on the field. At one point he took notes, saying he was jotting down players he wanted to watch when he catches the Browns on ''NFL Sunday Ticket.''
